IMPRCVEMENT IN DOUBLE-GONE REFLECTORS. I

Specification forming part of Letters Patent No. 129,088, dated July 16,1872.

To all whom it may concern:

Be it known that I, JEREMY W. BLIss, of the city and county of Hartfordand State of Connecticut, have invented certain new and usefulImprovements in Double-Cone Relectors; and, to enable others skilled inthe art to make and use the l same, I will proceed to describe,referring to the drawing, in which the same letters indicate like partsin each of the figures.

The nature of this invention consists of two tubular burner-rings, oneof which is smaller in its ring diameter than the other or outer.

ring. Each of these rings is provided with tubular arms, which connectand conduct gas from the the supply-chamber or hub to the rings. Eachring is supplied with gas from. the main kvsupply-pipe, independentlyone ofthe other, by means of stop-cocks, so that two rin gs-one havin g,say, thirty-six burn ers-can be used without the other; or the onehaving, say, eighteen burners can be used without the former; or the tworings may be used at the same time, making, say, fifty-four burners.

By this improvement large rooms, halls, public buildings, churches, &c.,can be lighted with less expense of fixtures, less gas, and produceperfect illumination.

In the accompanying drawing, Figure l is a partial perspective view ofthis improvement, showing nearly the whole device in detail. Fig. 2 is asectional view. Fig. 3 is a plan View of the two burner-rings.

a is a double-cone reflector. b is a burnerring, representing thirty-sixburners arranged in the upper side thereof. c aretubular gassupply arms,one end of which is tted into the inner side of the ring b, and theother end into the supply-chamber or hub d. e is a connectingsupply-pipe. One end is secured into the chamber or hub d and passes upthrough 'ing upon the supply-arms or pipes c, and is smaller in diameterthan the ring b,- and it is believed it will produce the best effect tomake this ring of such diameter that, when secured in its properrelative position with the ring b,

their two edges will be in about a parallel line with the outerconc-reecting surface. This ring is also provided with arms c whichconnect it with the supply-chamber or hub d, and through which the gasis introduced to the eighteen burners. Each of these burner-rings isprovided with one or more stop-cocks, h.

Now, it will be seenas has been already fully shown by actual practicein a room sixty by seventy feet square, thirty-three feet ceiling-thatby opening the stop-cock of the ring b', a very cheerful light will beproduced, so that personsin the furthest corner of this room can clearlyread a newspaper; and, by turning out the eighteen burners and lightingthe thirty-siX burners a still more cheerful light will be produced 5and, by again reopening or lighting the eighteen burners, making, inall, fiftyfour burners, the room becomes very brilliantly lighted, andis more perfectly accomplished than by device heretofore used.

I claim- The concentric rings b b', arranged in the same, or nearly thesame, plane relative to each other, provided with arms c c and suitablestop-cocks, when combined with the double-cone reflector a a', as shownand described.
